Overview

This article explains why a user is able to log in when their account is in the Blocked(Bruteforce) state.

The following settings are enabled:

  • Brute-force Protection enabled
  • Block Brute-force Logins - enabled

Applies To

  • Brute-force Protection
  • Blocked(Bruteforce)

Cause

Brute-force protection safeguards against a single IP address attacking a single user account.

Solution

Review the backend logs and check for which IP the user is blocked under User Management > Users > Search the user > Raw JSON .

 "blocked_for": [
    {
      "identifier": "abc@example.com",
      "connection": "Username-Password-Authentication",
      "ip": "11.22.33.44"
    }

The recent login is from a different IP address -12.23.237.116—which is why they are able to log in.

You can check the logs corresponding to the user under Dashboard > Monitoring > Logs:

user_id:"auth0|123456"
